Self-efficacy in language learning have been attracting interest recently. The construct is said to be a reliable predictor of language performance. This study is aimed at explaining the relationship of self-efficacy and speaking proficiency of male and females. It was administered to investigate whether self-efficacy correlates to speaking…

For many people, learning a second language as an adult is a challenging endeavor. Much interest in the study of adult second language learning has concerned the type of input that learners receive in their second language, with findings suggesting that second language learners are often exposed to a register of speech called 'foreigner talk' that…

With the increasing prevalence of autism diagnoses globally, the overall aim of this dissertation is to improve our understanding of the linguistic aptitude of autistic individuals. Given that the autism diagnosis is a spectrum, we rely on the Autism Quotient (AQ) test, which measures the quantity of autistic-like traits an individual possesses,…

The current study explores variation in phonemic representation among Spanish--English dual language learners (DLLs, n = 60) who were dominant in English or in Spanish. Children were given a phonetic discrimination task with speech sounds that: 1) occur in English and Spanish, 2) are exclusive to English, and 3) are exclusive to Russian, during…

Some listeners exhibit higher sensitivity to subphonemic acoustic differences (i.e., higher speech gradiency). Here, we asked whether higher gradiency in a listener's first language (L1) facilitates foreign language learning and explored the possible sources of individual differences in L1 gradiency. To address these questions, we tested 164…

This study was to assess the spoken vocabulary knowledge and its role in incidental vocabulary learning from captioned television. The participants were a total of 87 minority students learning English as a foreign language in Australia. The breadth of their vocabulary knowledge was measured with a vocabulary size test, while the depth of their…

Purpose: This study builds a new system for automatically assessing learners' speech elicited from an oral discourse completion task (DCT), and evaluates the prediction capability of the system with a view to better understanding factors deemed influential in predicting speaking proficiency scores and the pedagogical implications of the system.…

Language learners need to map a continuous, multidimensional acoustic signal to discrete abstract speech categories. The complexity of this mapping poses a difficult learning problem, particularly for second language learners who struggle to acquire the speech sounds of a non-native language, and almost never reach native-like ability. A common…

This longitudinal study of 17 American learners of French lies at the intersection of 2 complementary fields of inquiry in second language acquisition (SLA): language variation and change (LVC) and language acquisition during study abroad. Studies in LVC examine the nature and use of linguistic features that have more than 1 possible realization…

Metadiscourse, a linguistic means that is used in the production and organization of ideas, is vital in achieving successful communication. In language studies, metadiscourse in writing and speaking have been disparately investigated, where the former received more attention than the latter. Thus, the present study analyzes metadiscourse in the…

Recent longitudinal approaches to second language (L2) pronunciation development have prioritized developmental trajectories, highlighting individual variation in phonetic learning over time. Aligning with this research paradigm, the present study examined voice onset time (VOT) production in Spanish/b/and/p/ over two semesters of elementary…

This study investigated the role of cross-linguistic similarity in the acquisition of Russian initial stop contrasts by Chinese learners, addressing two specific research questions: (1) How similar are Russian voiced stops to Mandarin stops for Chinese learners?; and (2) How can the speech learning model (SLM) be applied to account for the…

In this investigation we propose new machine learning methods for automated scoring models that predict the vocabulary acquisition in science and social studies of second grade English language learners, based upon free-form spoken responses. We evaluate performance on an existing dataset and use transfer learning from a large pre-trained language…

This study investigated the constructs underlying second language (L2) word association (WA) with regard to three dimensions of lexical competence--size, organization, and accessibility--and the lexical performance of speech. One-hundred and thirteen Japanese learners of English completed a computer-delivered oral WA task along with three…

The present study aimed to investigate the relationship between self-actualization (SA) and speaking skill, creativity (C) and speaking skill, and also the interaction of both creativity and self-actualization and speaking skill to find out which of the two variables of SA or C can better predict speaking skill of the intermediate EFL learners. In…
